CAT3626 Datasheet (ON Semiconductor)

CAT3626, LED Driver

The CAT3626 is a high efficiency 1x/1.5x fractional charge pump with programmable dimming current in six LED channels.

To ensure uniform brightness in LCD backlight applications, each LED channel delivers an accurate regulated current.

Low noise and input ripple is achieved by operating at a constan
